Application filed December 7, 1926. Serial No. 153,163.

The present invention relates to giiis of the roller type, and the object lis to provide a novel apparatus in which `the ginning action is effective and thorough .both for long 5 and short staple, and is furthermore rapid in its action, .thus materially increasing the output.

A furtherobject is to provide mechanism whereby nails7 stones or other obstructions 1o will not cause injury or Vcreate dangerous conditions, but will pass readily'through Y porting bar and the knife member mounted f thereon, the stripper blade being also shown,

Figure 7 is a top plan view of the calfrier .bar and stripper blade A.mounted therein, Figure 8 is a front elevation of the kcarrier bar. l

Figure 9 is a 9-9 of Figure 3.

In the embodiment disclosed, a Lframe is employed, comprising end members 1Q connectcd bv` a suitable base 11, and having a -Y brace l2 secured to thecentral port-ion of the base 11 andbolted to the end members 10 between their upper and lower portions.

' The rear upper corners of the end members are cut-away, as illust-rated at 13, forming seats, upon which bearing boxes 14 are slidably mounted, that are adapted to be held by suitable bolts 15. Adjusting screws .16 serve to move the boxes inwardly. Journaled in these boxes is a shaft 17 having a squared portion 18, on which is mounted the body 19 of the gin roller. This body is covered with suitable material, such as strips of Walrus hide, shown at 20, diagonally wound on and secured to the roller body in a manner well understood. roller is rotated lby any suitable means in the direction indicated by the arrows in Figures 3 and5.

VLocated below o5 the roller'is a supporting sectional view on the line The bar 21 held by bolts 22 that pass through slots 23 inthe ends of the bar 21, these slots thus permitting the vertical adjustment of the Ysupporting bar.` Its lupward movement Lis secured by means. of adjusting screws 24 that bear against its lower side. 'In the upper edge of the bar ,is formed a longitudinal groove 25, constituting a seat, and in this seat is located the lower edge of` an upstandying knife member ,26,.having a sharpened upper edge 27 that lies alongsider the downwardly moving surface of the gin roller.- The blade is ysecured in'k place by U-shaped clamp plates 28 bearing against the front face ,of the bar and the lower margin kof the blade 26. These clamp 'plates are held in place by bolts 29. Spring plates 30, hav- Ving offset ends, also bear against the front face of the supporting bar 21 and the front face of the blade 26, their tension being obtained by bolts 31 (see Figure 6). As a consequence it will be evident that the upper portion of the knife member vwill rbe held yieldingly against kthe face of the roller and that said knife member can be verticallyv adjusted by adjusting the supporting bar 21. It will also be evident that the roller can be adjustedtoward and from the blade, as desired. i

Located in advance of the roller and knife member 26 is a carrier bar 32, the endsof which extend through the end members 1G of the frame and have terminal eyes 33 in which are fixed studs 34 held by set screws 35 and projecting onk opposite sides of the 'eyes 33. Flexible upstanding arms 36 are provided at their' upper ends with journal boxes 37 in which the studs 34 are pivotally engaged. The lower ends'of the arms 36 are bolted,as shown at 38 to vertically adjustableplates 39.l and these plates are in turn mounted on horizontally adjustable plates40 that are carried bythe outer sides vof the endmembers 10. As showny in Figures 3 and 9, the horizontal plates are held by bolts 41 passing through both plates,.and through the end members 10, and are horizontally adjustable by means ofadjusting screws 42, horizontal slots of course being provided in theplates 40 for thepassage of the clampingbolts 41. The vertically adjustable *platesY 39 are secured by the bolts 41 and have vertical `slots 43, through which said bolts 41 pass. The vertical adjustment of the 'vertically movable vcentral portion of plates issecured by adjusting screws fili threaded through ears formed on the upper ends of the plates 39, and bearing on the upper-.edges ofthe plates 10. It will thus be evident that the carrier bar is capa-` ble of longitudinal movement.

This movement is effected through the medium of a crank shaft 46 journaled in ay casing 4:7 that is carried by one of the end members 10. The crank of this shaft 46 has a journal boX 4S engaging it, and

' this box is connected to a flexible pitman 49.

The pitman is secured byfbolts 50 to the ablyV has its upper edge serrated, as shown at 52, and it is so' disposed that the upper edge Vof the knife member extends across the rear faces of the teeth and the interdental spaces of the stripper blade. The stripper blade `is mounted on the carrier bar by a series of bolts 53 that slidably pass through openings in thel carrier bar vand are held inv place by nuts 54 that are on the bolts and bear against opposite sides of the bar. lVith this'construction, it will be clear that the bar can be raised, lowered or shifted horizontally by moving the plates on which the flexible arms 86 are mounted, and in addi.

tion the stripper blade can be adjusted toward and from the carrier bar and there# fore toward and from the knife member by adjusting the bolts 53 in the carrier bar 32.

Mounted on this carrier bar and extending thereover is a rearwardly and downward-ly inclined feed table 55 that may be formed of corrugated .sheet metal. As shown in Figure 5, this table terminates short of the stripper blade 51 and isl adjustably held in place by screws 56 passing through .slots 57 in the table.

The operation of the structure is substantially as follows. lith the roller rotating in the direction indicated by the arrow and lwith the crank shaft 16 rotating, it will be evident that the downwardly moving` surlface of the roller passes by and in close association with the upstanding edge of the knife member, and that theserrated edge of the stripper bar operates directly in front of the same. If, now seed cotton is deposited on the table 55, it will be caused to gravitate rearwardly by reason of the reciprocation` of the table and the inclination thereof. Consequently the lint will be brought into contact with the downwardly moving face of the roller, andy adhering thereto, will -be drawn behind the stripper bar and knife member. It will therefore find its way the carrier bar 32, asv

downwardly and rearwardly behind the knife member, and over the inclined rear upper face of the supporting bar. The seed, however', will be held back, and, being dislodged by the reciprocating stripperblade,

will pass downwardly behind the table 55 due to the` space between Athe rear edge'of the table and the stripper blade 51, vthence said seed can gravitate between the carrier bar 32 and the front face of the blade, the space being left for that purpose. It is thought that this can be readily understood by referenceto Eigure 5. Any stones, nails or other hard obstructions willr be held away from the roller and knife member by the stripper so that these too will pass downwardly with Athe seed and consequently will not be brought into frictional engagement with the portion of the roller' that is engaged with the knife member. They therefore will neither obstruct the machine and its operation, nor cause dangerous conditions from their presence in the seed cotton. vIt has been found that with this apparatus, the cotton can be ginned with great rapidity and very effectively. 'Obviously any adjustmentthat is necessary can be obtained either by verstood that various changes in the size, shape,

proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
